WINDOW-SASH.

SPECIFICATION forming part of Letters Patent N o. 554,07 5, datedFebruary 4, 1896.

Applidfild October 2, 1895. Serial No. 564,421. (No model.)

T0 all whom t may concern.-

Be it known that I, CHARLES C. MILLER, of Brooklyn, in the county ofKings and State of New York, have invented a new and ImprovedIVindow-Sash, of which the following is a full, clear, and exactdescription.

This invention relates to window-sash.

A window-sash as ordinarily constructed and arranged within a casing isapt to shrink or swell with the atmospheric changes. Vhen the sash iscontracted it will rattle in the casing, and when expanded itisdifficult to raise.

The object of my invention is to obviate these objections.

My invention consists in providing a yielding attachment for the siderail or rails of a sash, and to which the weight cord is attached.

The invention further consists in the construction and novel arrangementof parts, as will hereinafter appear and be particularly pointed out inthe appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specication, in which similar characters of reference indicatecorresponding parts in all the views.

Figure l is a front elevation of a sash embodying my invention. Fig. 2isa section on the line 2 2 of Fig. l. Fig. 3 is a longitudinal sectionof a yielding attachment. Fig. 4 is a front view of a portion thereof,and Fig. 5 is an end view.

Referring to the drawings, A designates the lower sash, A the uppersash, and A2 the window-casing. I have here shown a yielding attachmentfor each side rail of the sash; but it is to be understood thatpractically the same result will be attained by attaching it to one siderail only. rlhe yielding attachment comprises a metal boxing B, open atits front and adapted to slidebetween the stopbead a and parting-bead cof the casing. A metal shell Bis secured to the side rail of the sash bymeans of screws. This shell B' is designed to iit snugly, yet movably,within the boxing B. As a means to provide a good hold for the screwsemployed for securing the shell to the sash-rail, I employ a metalreinvention.

force-strip b, placed'within the shell and having tapped holes in whichthe screws engage.

Springs B2 are attached to the reinforcestrip b, and their free endsbear against the inner surface of the boxing B, as shown in thedrawings. I have here shown three springs; but more or less may beemployed withoutA departing from the spirit of my in- A guide pin orscrew b" projects from the lower end wall of the shell through aguide-slot h2 in the lower end wall of the boxing, and a sash-cord b3 isattached to the upper end wall of the shell and extends through aslot-opening b4 in the upper end wall of the boxing, over a pulley whichis here shown as located on top of the casing A2.

It will be observed that the shells B for a sash extend slightly beyondthe surface of the stop-bead and parting-bead, and that the centralfastening-screws a2 serve as pivots on which the sash may be turnedafter removing the other screws, thus making it convenient to clean theouter side of a glass by a person standing within a room. y

By the construction shown and described it is clear that a sash may beeasily removed, when desired, without Iirst removing a stopbead, as isnecessary with sash of the ordinary construction.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. The combination with a window-sash, of a yieldingextension for a side rail thereof, comprising a metal boxing open at itsfront and adapted to slide in a window-casing, a metal shell secured tothe side rail of the sash, a reinforce-strip in the shell, springssecured to said reinforce-strip and bearing against the inner surfaceofthe boxing, a pin extended froin the lower end of the shell through aslot in the lower end of the boxing and the said shell having an openingin its upper end wall for the passage of a sash-cord, substantially asspecified. Y

2. The combination with a window-sash, of yielding extensions for theside rails thereof, comprising a metal boxing adapted to slide in thewindow-casing, metal shells secured to the side rails of the sash andhaving theiil side portions extending into the boxings, the said shellsbengextended toward the Center of the Window slightly beyond the stopand parting beads of a easing whereby the sash may be turned on centralhorizontal pivotal Connections With the shells, leinfoicest1ips in theshells, springs secured to the reinforce-strips and bearing aga-inst theboxings, and a guide- 1 o pin at the lower end of the shells,substantially as specified.
